Explosive on car kills hotel-casino worker

? A device left in a casino parking garage exploded early Monday, killing a man who tried to pick it up off the top of his car, authorities said.

The device exploded shortly after 4 a.m. on the second floor of a parking garage behind the Luxor hotel-casino, said Officer Bill Cassell, a police spokesman. He declined to describe the device but said initial reports that it was inside a backpack were wrong.

The blast was not a terrorist act but an apparent murder of a man who worked at a business inside the hotel, he said, adding that the case was being investigated as “a homicide with an unusual weapon.”
